Relation Between Arc Radius And Angle Arc length = [radius • central angle (radians)] Arc length = circumference • [central angle (degrees) ÷ 360] Proof of the trigonometric ratios of complementary allied angles Two acute angles are complementary to each other if their sum is equal to 90°. In a right … Read more
Area Of Triangle The area of triangles can be found by using the following formula: Area = Base × height / 2 The red line represents the length of the base (call it b if you want) and the blue line represents the length of the height. To get the area, just multiply the value … Read more
Distance Between Two Points Here is how to calculate the distance between two points when you know their coordinates: Let us call the two points A and B We can run lines down from A, and along from B, to make a Right Angled Triangle. And with a little help from … Read more
